1. Lub incubation ntawm cov qe yug me nyuam
Incubate los yog hnyav qe. Tom qab txhua yam yog npaj txhij, lub qe yuav tsum tau pw thiab incubation yuav pib. Qhov kub ntawm kev yug me nyuam qe yog feem ntau qis thaum lub sij hawm cia. Txhawm rau kom rov qab kho qhov kub thiab txias hauv lub tshuab sai sai tom qab cov qe tso, lub qe khib nrog lub tais yuav tsum raug thawb rau hauv qhov cub kom sov ua ntej txog 12 teev ua ntej hatching. Lub sij hawm tso qe tuaj yeem yog tom qab 4 teev tsaus ntuj, yog li nws tuaj yeem ntes nrog hnub thaum muaj coob tus menyuam qaib hatch, thiab ua haujlwm yooj yim dua. Txoj kev tso qe sib txawv raws li qhov tshwj xeeb ntawm lub incubator. Feem ntau, cov qe tau muab tso rau ib zaug txhua 3 mus rau 5 hnub, thiab 1 txheej ntawm cov qe tso rau txhua zaus. Thaum nkag mus rau incubation, txoj hauj lwm ntawm txhua lub qe tais ntawm lub qe khib yog staggered kom cov "cov qe tshiab" thiab "cov qe qub" tuaj yeem kho qhov kub ntawm ib leeg. Niaj hnub nimno incubators nrog qhov cua zoo thiab kev tswj xyuas qhov kub thiab txias tuaj yeem sau nrog cov qe qe ntawm ib lub sij hawm, los yog muab cov qe tso rau hauv partitions thiab batches.
2. Tswj ntawm incubation tej yam kev mob
Txij li thaum lub incubator tau mechanized thiab automated, kev tswj yog yooj yim heev, feem ntau them sai sai rau qhov kub thiab txias hloov, thiab soj ntsuam qhov rhiab heev ntawm kev tswj qhov system. Siv sij hawm ntsuas thaum ua tsis tiav. Ua tib zoo saib xyuas cov av noo hauv lub incubator. Rau incubators uas tsis yog-automatic humidity tswj, dej sov yuav tsum tau ntxiv rau lub tais dej nyob rau hauv lub sij hawm txhua txhua hnub. Nco ntsoov tias lub gauze ntawm lub hygrometer yuav ua kom tawv los yog kis tau nrog plua plav thiab fluff nyob rau hauv dej vim yog kev ua ntawm calcium ntsev, uas cuam tshuam rau evaporation ntawm dej. Nws yuav tsum tau ua kom huv si thiab yuav tsum tau ntxuav los yog hloov tsis tu ncua. Cov yeeb nkab dej ntawm hygrometer tsuas muaj cov dej distilled. Cov kiv cua thiab cov qe racks ntawm lub incubator yuav tsum tau ceev kom huv si thiab tsis muaj plua plav, txwv tsis pub nws yuav cuam tshuam rau qhov cua hauv lub tshuab thiab kis cov embryos uas hatching. Koj yuav tsum nco ntsoov xyuam xim rau kev ua haujlwm ntawm lub tshuab, xws li seb lub tshuab ua kom sov, seb puas muaj lub suab txawv txav hauv lub tshuab, thiab lwm yam. Qhov kub thiab txias, av noo, qhov cua thiab lub qe tig yog ib txwm tswj nyob rau hauv qhov zoo tshaj plaws ntau yam. .
3. Noj qe
Txhawm rau kom nkag siab txog kev loj hlob ntawm embryos thiab tshem tawm cov qe tsis muaj menyuam thiab cov embryos tuag nyob rau lub sijhawm, feem ntau peb zaug ntawm incubation yog nqa tawm nyob rau 7th, 14th thiab 21st lossis 22nd hnub ntawm incubation, thiab kev loj hlob ntawm embryos yog soj ntsuam los ntawm lub qe. .
⑴ Embryo qe loj hlob ib txwm. Los ntawm kev txhaj tshuaj lub taub hau, nws tuaj yeem pom tias lub qe qe loj tuaj thiab tig mus rau ib sab. Lub embryo tau tsim los ua kab laug sab, nrog pom tseeb ntawm cov hlab ntsha nyob ib ncig ntawm nws, thiab cov ntsiab lus ntawm lub embryo tuaj yeem pom. Co lub qe me ntsis, thiab lub embryo yuav txav nrog nws. Los ntawm daim duab thib ob, nws tuaj yeem pom tias sab nraud ntawm chav degassing yog npog nrog cov hlab ntsha tuab, thiab cov hlab ntsha allantoic raug kaw ntawm lub taub me me ntawm lub qe. Los ntawm peb daim duab, nws tuaj yeem pom tias lub embryo tsaus nti thiab cov huab cua chamber loj, maj mam inclined mus rau ib sab, lub ntug inclined curled, thiab tsaus ntxoov ntxoo flash nyob rau hauv cov huab cua chamber, thiab lub qe kub thaum kov lub qe. .
⑵ Tsis muaj phev qe. Lub taub hau txhaj tshuaj qhia tias lub qe yog xim daj ntseg, thiab tsis muaj kev hloov hauv nws sab hauv. Tus duab ntxoov ntxoo ntawm lub qe yolk pom faintly, thiab cov hlab ntsha tsis pom.
⑶ Tuag embryo qe. Cov embryos tuag pom nyob rau hauv lub taub hau txhaj tshuaj tsis muaj cov hlab ntsha, thiab cov ntsiab lus ntawm cov qe yog pos huab thiab ntws, los yog muaj cov seem ntshav qhov muag, los yog cov duab ntxoov ntxoo ntawm cov embryos tuag yuav pom. Cov qe embryo tuag pom hauv Sanzhao muaj cov pa cua me me, thaj tsam tsis paub meej, thiab turbidity; cov xim hauv lub taub hau me me ntawm lub qe tsis yog xim dub, thiab nws xav tias txias rau qhov kov.
4. Muab qhov kev txiav txim
Hnub tim 21 los yog 22 hnub ntawm incubation, txav cov qe embryonated mus rau hauv lub lauj kaub tais diav los yog hatcher, thiab kho qhov kub thiab av noo kom tau raws li cov xwm txheej rau hatching. Kev tso kawm yog nqa tawm tib lub sijhawm raws li daim duab thib peb.
5. Khaub ncaws
Thaum lub embryo loj hlob ib txwm, cov menyuam qaib pib hnia tom qab 23 hnub. Lub sijhawm no, lub teeb pom kev hauv lub tshuab yuav tsum tau muab tua kom tsis txhob muaj menyuam qaib los ntawm kev cuam tshuam cov menyuam qaib. Thaum lub sij hawm hatching, nyob ntawm seb qhov teeb meem ntawm lub plhaub, tshem tawm cov qe khoob thiab cov me nyuam qaib nrog qhuav kom yooj yim mus txuas ntxiv hatching. Feem ntau, cov menyuam qaib tsuas yog xaiv ib zaug thaum lawv ncav cuag 30% txog 40%.
